About this study

Official title: Effects of Alternate Day Fasting and Exercise on Body Weight, Visceral Fat, and Metabolic Parameters in Overweight or Obese Adults: A Randomized Controlled Trial

Alternate day fasting is known to be helpful to control weight and have a positive effect on insulin resistance and cardiovascular risk factors. However, there have been no studies on weight reduction program combining alternate day fasting with exercise which preserves lean mass in Korea. The purpose of this randomized clinical trial is to examine the effects of alternate day fasting and exercise on weight reduction, visceral fat, and metabolic parameters in overweight or obese adults.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Alternate Day FastingBehavioural

    During the 8-week intervention, participants consumed 25% of their daily recommended energy intake (approximately 500 kcal) on each "fast day" (24 h), and consumed food ad libitum on each "feed day" (24 h). The "fast day" and "feed day" were repeated every other day, and the "fast day" occurred 3 days per week.

  • ExerciseBehavioural

    During the 8-week intervention, participants visited the research center gym at least three times per week and received exercise logs. Each exercise session began with 5 minutes of warm-up and ended with 5 minutes of cool-down. Resistance training was performed using weight training machines, barbells, and dumbbells for 40 minutes. Aerobic exercise was performed on motorized treadmills for 20 minutes.

Questions about this trial

What is this clinical trial studying?

A study testing Alternate Day Fasting and Exercise in people with Overweight and Obesity, run by Gangnam Severance Hospital.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in body weight (time frame: baseline, 8 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03652532, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Aug 2018.
